Possible dark matter-deficient twins discovered in the Fornax Cluster
Astronomers have identified a possible new example of one of the universe's strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC 240, on the outskirts of ...
Space telescopes are now overwhelmed by satellite trails
Unfortunately, there's more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA's Ames Research Center, reports that 73.3% of images the agency's new SPHEREx ...

What happens to a star that captures a primordial black hole?
We don't know whether theorized primordial black holes (PBH) are real. If they are, they formed in the very early universe, when physics was much different. They had no stellar progenitors and were created by the direct collapse ...

Black hole feeding bursts may explain JWST's Little Red Dots in early universe
A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on ...
Astronomers discover the earliest known flickering quasar
A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and ...

MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk
Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational ...
Did this star eat its planets? A new study offers clues on 'chemical paradox' of a binary system
Astronomers have investigated a puzzling binary star system in which two stars that may have formed together now show dramatically different chemical compositions. The new study, uploaded to the arXiv preprint server on May ...
Webb unveils young stars across every stage of formation
For this NASA/ESA/CSA James Webb Space Telescope Picture of the Month, we return to the constellation Orion (the Hunter), a location familiar to Webb. This area of the sky is replete with star-forming clouds that make up ...
